Brazilian court overturns verdict against policeman involved in 1992 prison massacre

Human rights groups, including Amnesty International, have reacted with shock and indignation towards a Brazilian court’s decision in favor of a police colonel implicated in the 1992 Carandiru prison riots. Ubiratan Guimares was convicted in 2001 of commanding police to kill over 100 unarmed prisoners during riots in Sao Paolo’s Carandiru Prison.
